Arkyic Stone

Arkyic Stone is a block in Mindustry's environment category that denotes a natural terrain tile rather than a player-placed building; it appears on maps as part of the game’s geology and serves as environmental scenery and obstacles within levels. As an environment block, Arkyic Stone is not itself a craftable item or unit and is primarily referenced for map layout, traversal and interactions with other systems (such as mining or placement restrictions) rather than direct production or research. Only the name and category are specified for this entity.
